Dogs will also have bad breath, just like humans. And it will all come from bacteria building up in your dog’s mouth. You wouldn’t want to get slobbery kisses from your dogs that have bad breath because it will be yucky.
But if you get your dog’s teeth regularly brushed and cleaned, they won’t have bad breath anymore. Plus, those particles won’t build up inside your dog’s mouth and create plaque. Aside from a bad breath, they will have tartar build-ups, which only a professional can get into.
